ADJUSTING DEVICE FOR PAPER-CARRIAGES OF CALCULATING-MACHINES.

; culat-ing-Machines, of which't-he following is a specification.

This invention relates to an adjusting device for the paper carriages of calculating machines of the type provided with printing mechanism. In such machines it is of great importance to move the paper carriage rapidly backward and forward bet-ween a number of columns, and adnst it in any required position. For this purpose the carriage is connected by levers to a stud which is guided in a slot provided in the front wall, and on releasing the hand therefrom. it auto-matically adjusts itself at the required position, when seized itis again released.

In the accompanying drawing, Figure 1 shows a part of the front wall of the machine, with the tabulator in front elevation. Fig. 2 is a plan of a form of adjusting -means, the front Wall being partly broken away. Figs; 3' and 1 show a gripper guide in the slot of the front Wall, in two different positions. 4 Figs. '5 and 6 are sections at right an les to Figs. 3 and 4.--showing the stud.

The base plate '1, of the writing device, is rigidly connected to the front wall of the machine by rods 2 and 3. In the hold Wall 4}, provided a guiding siot 5, for the stud 10, and alcove the slot are provided holes 6, for the tabulator pins 7. ()n the inclined upper har' of the front Wall is provided a scale 8. The stud 10 is guided in the slot 5 by means of a slide 9. Through the stud 10 passesaspring operated pin 12 whicln'at its rear end, is provided with a milled conical part 13 engaging milled walls of a guideway 14. I

If the stud 10 is grasped between-the first and middle fingers of the left hand, and then the thumb is pressed on the pin 12, the

stud- 10 may be moved outwardly causing the part 15, which engages pins 19 of the slide 9. Simultaneously, the conical partof the pin 12. which is controlled by the spring 11, is moved out of the slot 1A1, so

that the slide can b moved to the right, or the left, in the slot 5, hy means of the stud Specification of Letters latent.

10. On the part 15 and rigidly connected thereto, is rotatably mounted on the pin 16, the gripper plate 18, wh ch engages with part 15 by means (Jfspriug members 17. o

The gripper plate is provided on bot-h'sides with hooked arms. 'lhepins 1t) projecting into the part 15, prevent rotation thereof. Into the holes 6, above 'the slot 5, the tabulator pins 7 are inserted, and when the stud. 65

1.0 is moved laterally, the ctn'rcsponding hooke'd arm of the gripper 1S hangs above the pins T, previously arranged according to the headings to be made, whereby the paper carriage connected to the pin 12 is adjusted, at the required position (Fig. 3). If this adjustment is to be changed, the stud 10 is again seized in the manner hercinbe fore described,.a1ul by pressing. on the pin 12, the conical part 1 :3 is'moved out of the slot 14, whereupon the gripper 18, provided on the slide 15, -an be moved over the tabulator pin. 7 by rotating about "the pin 16 (Fig. 4), so that the carriage again becomes freely movable. If it is desired that the gripper 18, as soon as a large number of tabulator pins 7 have been inserted, should pass over a number of separate tabulator pins, so that the corresponding heading may remain free, then the stud 10, by pressing on the pin 12, is simultaneously moved such a distance that the tabulator pins 7 remain behind the gripper 18 and the gripper arms can slide over these. Shortly before reaching the required stopping position. the gripper 1Q is allowed to slide back and one of the gripper arms 18 catches on the corresponding tabulator pin 7, so that the paper carriage again remains stationary.

The connection of the stud 10, or the spring operated pin 12, to the paper carriage, is eifected in the following manner To the conical part 13 of the pin 12 there is secured. by means of an eye 12, a link 21 which is hinged to the lever 22. The lever 1 92 is pivoted to a pin 23, provided on the underside of the base plate 1. At 2 1, there secured to the rod 22 a lever 25, of which the other end 26, is pivoted to a rod 27.

The rod 27 is pivoted at 28, in the support 1 29, on the front wall 4, and its other end is connected at 30 to a rod 31, which is connected to the member 33, rigidly secured to (not shown), bythe the paper carriage, ivot 32. The columns 3 1 and 35, secured to the base plate 1, serve to. support a rail To the rod 27 is connected a roller 37,

which'runs on the rail 36. On a second rail 40, which is secured to the member. '39, of

the support 29, and at 38, to the connecting rod 2, runs a roller 41 provided on the rod 22, The paper carriage can be adjusted in any other suitable intermediate position outs1 e movement, at any position, they can heremoved completely, as they are only to facilitate the frequent reciprocal movements between equal fixing points. a

Iv claim I 1. In' combination with a paper carriage 'for calculating machines having printing mechanism, of a frame portion having a milled or roughened braking surface and a slideway adjacent thereto, a milled braking element engaging said surface, a block slidable in said Way, a pin connected with said element. and slidable in said block, a sleeve on said pin, a spring normally acting to hold said sleeve and pin in normal positions tomaintain said element in engagement with said braking surface, and link mechanism connecting said pin with said carriage, substantially as described.

2; In combination with a paper carriage for calculating machines having printing mechanism, of a frame portion having a milled or roughened braking surface and a .slideway adjacent. thereto, a milled braking element engaging said surface, a block slid.-

able in said way, a pin connected with said elen'ient and slidable in said block, a spring for normally holding said pin in a position to engage said element with said surface, and link mechanism connecting saidpin with said carriage, substantially as described.

3. A device of the class described comprising in combination, a carriage, a frame portion, a pin adjustably mounted on said frame portion to be moved longitudinally thereof, brakings on said pin, a spring for normally holding said'braking means in an acting position to lock said pin in an adjusted position, and mechanism connecting said pin with said carriage, substantially as described.

4. A paper carriage adjusting device comprising n combination a frame with a slideway therein, a block slidable in said way, a pin slidable in.said block and having braking means to lock the block in an adjusted position, a sleeve on said pin, a spring for holding said pin and sleeve in normal positions, a spring controlled gripper on said sleeve, and tabulator pins adjustable on said frame and disposed in the path of said gripper. v

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
